ABSTRACT:
A vapor-liquid contacting process is disclosed which may be used in gas treating, absorption or in fractional distillation. The process is characterized by the utilization of a liquid support plate (tray) having a flat vapor-liquid contacting area formed by uniformly spaced parallel members which provide long narrow passages for the rising vapor. The process is especially useful when a low pressure drop through the liquid support plate or a high tendency of the liquid support plate to prevent weeping is desired. The process allows higher operating capacity than the use of valve-type liquid support valves.
